In fictional acronyms, priorities are reversed. It's not so important that the full name be clear, memorable and to the point; it matters much more that the actual acronym spell out a word or phrase, preferably a meaningful, impressive (or just plain funny) one. This results in "backronyms", acronyms created before the names they allegedly stand for—if the acronym even stands for anything at all.

For instance, no writer would have allowed New York's police force to come up with the abbreviation "NYPD". That can't even be properly pronounced. No, they'd have named it, ehm... something like the |Central Organization of Police Specialists. It doesn't matter so much that the full title is essentially meaningless—we got it to spell out COPS! Heck, we can even sell some toys now! Or, you know what would be better than COPS, would be JUSTICE! So what does JUSTICE stand for? Nothing. That's right, we don't even need it to stand for anything if we don't want it to!

This isn't just for names that are cool, of course. It's also for names which accidentally hint at the true nature of an organization (e.g., a pro-tobacco council with the name CHOKE), or just as "accidentally" spell out something naughty or undignified.

Of course, sometimes a neat acronym can be derived from a sensible name. This is what we call the best of both worlds. (Or should that be the best of both words?)

For even more fun, make it a Recursive Acronym, or add Acronym Confusion. In government, military, and engineering contexts, this is absolutely Truth in Television, probably because there are so many acronyms in those fields that nobody can remember them if they don't have a nice mnemonic.

Technically it's only an acronym if you pronounce it as one word (like "laser" or "scuba"), and if you spell out the letters, it's an initialism. In practice, most people just use "acronym" for them all, so feel free to add them as examples.
